DUCTILE IRON PIPES AND FITTINGS
Strategic Partnership with Jindal Saw Group
Jindal Saw Limited the pioneer in the tubular industry
Jindal Saw’s ductile iron (DI) pipes have high quality mechanical properties, in addition to high durability and strength, which make them ideal for high-pressure applications. Ductile Iron Pipes are used extensively in systems transporting portable water, industrial water, irrigation water and pressure sewage.
Ductile iron is produced by treating the molten low-sulphur base iron with magnesium under closely controlled conditions. The starting change in the metal is characterized by the free graphite in ductile iron being deposited in the spheroidal or nodular form, leading to maximum continuity of metal matrix thereby forming a stronger and tougher ductile material with high ductility and impact strength.
